Review on Performance Tool Mechanics M592DB Impact by Rod Evans

Haven't used these with impact tools but like them for general hand use. They are very heavy with a good fit and finish. I have used them with 5ft breakers and found them very strong. I have broken 1/2" drive extensions while using these sockets without ever damaging the heads. I only paid $10 for the set and will buy a metric set if I ever find one for the same price. Update 2021. I used these sockets all the time. Now I have a 5 hp compressor. 60 gallons running a 1/2 inch IR percussion gun is just as good today as it was 10 years ago. Bring something with you.
